Safety and Warranty
ENVIRONMENTS, WORKING AND PASSING PLACES
The work environment must answer to the directive 89/654/CEE requirements. In the working area no foreign
objects can be present. The employer, in the directive of 89/391/CEE, must follow the measures promoting the
safety and health of the workers during the work. They must eliminate or reduce the residual risks as foreseen
in the manual.
WARNINGS ON THE RESIDUAL RISKS
RESIDUAL RISK DUE TO THE FIXED PROTECTIONS REMOVAL, INTERVENTIONS ON BROKEN/WORN
PARTS
The operator must not try to open or remove a protection measure or tamper a safety device.
In the phase of maintenance and cleaning, and during all further manual operations that
happens to introduce the hands or other body parts in the machine’s dangerous areas, a
residual risk remains due above all to:
1. Hitting with machine manufacturing parts.
2. Grazing and/or abrasion with machine rough parts.
3. Injury from the sharpened parts.
4. Lacerations from a tool having sharpened parts.
The operator and maintenance personnel must be skilled for the intervention connected to the manual
operations with open protections, must be trained on joined consequent risks and must be authorized from a
responsible person.
PROTECTION DEVICES ON THE MACHINE
The machine protections and safety devices must not be removed. If they must be removed for
extraordinary maintenance requirements, some measures will have to be immediately adopted.
To put in evidence and to reduce amount of danger. The reassembling aspect of the protection or safety
devices must happen as soon as the extraordinary circumstance has completed.
The machine transmission parts are completely isolated by means of xed protections which do not allow
access improper objects. For all safety functions including the control and check systems, well-tested
components and safety principles have been used.
Grater group:
1. Taking into account the machine’s modality and use, the moving elements are not isolated from the
protections and safety devices.
2. On the handle and pressure group, a micro switch is placed, which stops the grater roll rotation so it is
possible to access the grater mouth.
3. Fingers are prevented from accessing the grater roll as there is a xed protection piece to stop this.

PACKING REMOVAL – OPENING MODALITY
PACKING DESCRIPTION – HOW TO GET RID OF THE PACKING MATERIAL
The machines are package so that the liquids inside and organic matters are not present. There is a
polyethylene cover around the machine which is then inserted in a cardboard box of adequate size. The empty
spaces within the box are occupied with ll material.
Do not waste the packaging, but store it for possible transportation or locate a recycling agency for disposal.
It is an employer’s obligation to be acquainted of the laws in its own country and observe these legislations. It
is forbidden and liable to nes to leave the machine and electric equipment in the environment.
PREPARATION PRELIMINARY OPERATIONS
STABILITY
The machine stability is designed so that in normal functioning conditions, taking into account the climatic
conditions, the machine can be used without reversal risk, fall or inopportune movement. Taking into account
the conformation and the position of the machine, it will function without fastening it to the working ground.
GRATER ROLL ROTATION
The operations indicated must be performed by the maintenance person (skilled personnel
in the electric maintenance eld of industrial machinery). For machines fed with three phase
voltage (3 PE AC 400V 50Hz), slacken lightly the blockage wheel to not have a strong
pressure on the drilled plate for the cutting knife. When turning on, verify the Archimedean
screw / grater roll rotates counterclockwise. If there is clockwise rotation, switch off the
machine, disconnect the plug, disassemble it, disconnects the two phase conductions and
invert their position.
FUNCTIONING DESCRIPTION
The control devices are designed and manufactured to handle normal service stresses and strains. The control
devices are clearly visible, locatable and marked distinctly. The main control devices are shown:

Installation and Operation
TYPE / COLOUR REFERENCE / DESCRIPTION
Button / Black “0” / button for the machine stop control
Button / White “1” / button for the machine start control
STARTING
The machine only starts with a voluntary action on the control device: white button “1” for the starting control.
STOP
For the stop control push the black button “0”. In case of momentary or extended stop, all food products must
be removed to get the machine to function again.
FUNCTIONING SAFETY
If the machine is under stress or is exposed to long functioning times or overload, the thermal protection
function will stop the machine. In this case, wait until it is completely cooled before proceeding to the starting
function.
VOLTAGE LACKING
In the case of the electric feeding breaking off of the machine and being disconnected, the machine will only
restarted after the electric feeding is back or there is re-connection to the power source.
STARTING
The machine only starts with a voluntary action on the control device: white button “1” for the starting control.
STOP
For the stop control push the black button “0”. In case of momentary or extended stop, all food products must
be removed to get the machine to function again.
FUNCTIONING SAFETY
If the machine is under stress or is exposed to long functioning times or overload, the thermal protection
function will stop the machine. In this case, wait until it is completely cooled before proceeding to the starting
function.
VOLTAGE LACKING
In the case of the electric feeding breaking of if the machine is disconnected, the machine will only be restarted
after the electric feeding is back or there is re-connection to the power source.
PRESSURE OPENING - ONLY FOR UNITS WITH MICRO SWITCH
Lifting the handle of the grater mouth stops the machine immediately because of the safety micro switch
function. The machine can be restarted by lowering the handle and closing the mouth of the machine and
pressing the on switch again.

Installation and Operation
CONTROLS AND VERIFICATIONS BEFORE STARTING
VERIFICATION / CONTROL MODALITY AND CHECKS
Check that:
• Extraneous objects aren’t on the machine, inside the
grater mouth and in dispensing zone of the grated
product.
Check the cleaning:
• Of the grater mouth, of the pressure and grater roll.
• The external surface of the machine.
Check the integrity:
• Of the xed protections.
• Of the machine body, grater mouth, pressure and the
grater roll.
Check the functionality:
• Of control system parts / control about the safety.
• Of the control devices.
Check the presence:
• Of strange noises.
• Of oil trails on the ground and on the Archimedean
screw.
Visually check the indicated parts, check if
objects or extraneous objects around the
machine. Make sure there is not food product left
over. In case of its presence, remove them.
Visually check all parts and surfaces to verify
their cleaning. Disassemble to check internal
parts. In case of mold or other types of dirtiness,
follow the cleaning procedures indicated in
chapter 5.
All xed protections must perform their function.
Verify the integrity of the external surface. The
parts must be replaced at rst sight of erosion or
breaking.
All devices must perform desired function. The
actuators and all parts must be changed at rst
sight of erosion or breaking.
If there are strange noises, for example a seizing
of mechanical break, stop immediately and
contact maintenance personnel. Check during
work and at the end of every use. Check if there
are oil trails present. If there are any uid drops,
stop immediately and contact maintenance
personnel.
Possible changes in parts must happen with manufacturer original parts or at least of quality, safety and
equivalent characteristics. For analysis, contact the Authorized Assistance Center.
